Interrupted between here and there, follow the path. Likely a cable or a solder gone flaky.

No schematic? I can only see +5V_USER (C215), not more things =/

Bottom Right of the schematic you linked, "User 5V" start there and trace back or forward to find the fault.

5V_User, pin12 of PSU?

Maybe Amiga 2000 doesn't have 5V line in video port:

Just noticed the trace between EMI211 and pin23 was blown :hammer:
